VALVE.

Application led August A10, .1922, Serial No. 580,944. Renewed March 27,1926.

The present invention relates to tire valves and more particularly tocap closures for such valves. y

According to the present invention I provide a cap closure adapted tofunction both as a valve cap and a dust cap, the parts being soco-related that either` or both may be quickly attached or detached.This permits the quick application of a pump coupling when it is desiredto inflate the tire, and the'quick detachment of the entire closure whenit is desired to remove the tire from the wheel rim. The invention alsocontemplates the use of suitable packing means whereby any leakagethrough the tire valve past the valve cap is effectively prevented, andfor precluding the entrance of dirt, moisture and the like from gaininaccess to either the interior or exterior o the valve casing. It is alsoan object of the present invention to have the inner end of the dust capengage within the opening in the felly around the valve casing 1nmountings where a felly clamping nut is not used, and thereby preventundue lateral movement and cantlng of the valve casing. Certain otherfeatures of improvement are also provided as Will be hereinafter morefully set forth.

In the drawings wherein I have shown the preferred embodiments of myinvention:

Figure l is a longitudinal section of a portion of a Wheel felly, rimand inner tube showing one embodiment of the invention applied over avalve casing passing through the felly, the cap closure being shownpartly in section and partly in elevation.

Fig. 2 is a longitudinal section of a modification of the cap closure ofthe present invention applied over a valve casing, the latter beingshown in elevation.

Fig. 3 is an elevation of the valve cap shown in Fig. 2.

Fig. 4 is a longitudinal section of a slight modification of the valvecap shown in Fig. l mounted upon a valve casing, the latter and thepacking engaging the valve cap being shown in elevation.

Referring first to Fig. 1 of the drawings let A indicate a portion of aWheel felly having a rim B mounted thereon, and an inner tube C mountedon said rim. The inner tube carries a valve casing D secured theretothrough the medium of the enlarged foot E casin on the valve casing, thewasher F, the spreader G and the clamping nut H, as is common practice.vThe valve casing passes through an opening I in thefelly of slightlylarger diameter than said casing as is the usual practice.

Accordin to the present invention I provide a cap c osure for theprotruding portion of the valve casing, said closure bein adapted tofunction both as a valve cap and as a dust cap. This ca closure isindicated generally by the letter It and consists of the valve capportion L and the dust cap portion M, the parts being so co-related thateither or both may be qulcklv attached or detachcd from the valvecasing. The valve ca L is internally threaded to engage and sustantially wholl enclose the reduced nipple portion N o the valvecasing, the open end of the cap being Unthreaded and formed with aninwardly tapered surface adapted to seat against and enclose a suitablepacking O carried by the valve casing and formed with an outer wall taered complemental to the taper on the va ve cap. The packing Opreferably rest against a shoulder d on the valve casing formed betweenthe reduced nipple and the casing proper and seats in a recess orannular groove P formed on the nipple ad'acent the shoulder on the valvehe dust cap portion M consists of a ho low sleeve adapted to slide overthe valve casing said sleeve having an opening in its top adapted topermit the passage of the nipple therethrough and a fiange m surroundingsaid opening adapted to seatagainst the shoulder d on the casing.Preferably the opening in the top of the dust cap portion is of a sizeto engage the periphery of the packing O at its base. It is alsopreferable that the valve cap L be provided with a packing Z in itsbottom face adapted to form a seal with the flange m at the top of thedust cap portion and thus further protect the exterior of the valvecasing against the ingress of dirt, moisture and the like. As shown inFig. 1 the lower end of the dust cap portion seats within the opening Iin the felly7 from which it will be appreciated that the cap closure isadapted to accommodate and entirely enclose valve casings which protrudethrough the felly to different degrees. By having the lower end of thedust cap seat within the opening in vas a further protection for theexterior of the valve casing, said lining also providing frietionalengagement between the dust cap portion and the casing whereby theformer may be securely held on the latter without the aid of othermeans. To holdthe lining in place within the member M the lower end ofsaid member is flanged inwardly as shown at m. The flange m may alsoserve as a seating face for the dust cap portion against the rim nut forit will be understood that this type of cap closure is primarilyintended to -be used where a rim nut is employed. 20

In Fi 4 I have shown the valve cap L minus t e packing Z employedwithout the dust cap portion. When so used the cap forms a seal with thepacking O which effectively prevents the loss of any air which may passup through the valve insides in cases where such insides have becomedefective. In the diderent forms of valve caps herein shown it will beunderstood that the exterior thereof may be of any desired shape butreferably provided with a milled or knur ed surface whereby manipulationoi the cap will be facilitated.

To inflate a tire provided with the cap closure of the present inventionall that is necessary is to remove the cap L and attach the pumpcoupling tothe nipple N. On the other hand if the tire is to be removedfrom the wheel rim the dust cap portion M is pulled od the casing afterremoval of th'e cap L. It will thus be seen that the ca closure of thepresent invention effectively functions as a combined quick detachablevalve cap and dust cap.

While I have herein shown and described preferred embodiments of myAinvention I do not wish to be limited to the specic constructionsdisclosed since various changes may be made therein without departingfrom the spirit of the invention.

What I claim is:

1. The combination with a valve casing having a nipple ofreduceddiameter providing a `shoulder between the body of said casing and saidnipple, and a dust cap comprising a dust cap portion and a valve capportion, the dust cap portion being adapted to slide down over the valvecasing and having an opening therein for the valve, and the va ve capportion being adapted to engage the nipple to hold the dust cap portion1n place, of a packing having a tapered outer wall resting on saidshoulder and seating against said nipple, the opening in said dust capportion andthe valve cap portion being a apted to engage the taperedwall of the packing. v

2. In combination, a wheel felly having an opening therein adapted toreceive a tire valve casing, a valve casing of somewhat smaller diameterthan the opening, extendino' therethrough, and a dust' cap for the va vecasing having a part extending into `\the felloe opening, said dust capcomprising dust cap portion of a length to almost entirely enclose theportion of the valve casing which extends through the felloe, adaptedt-o slide down over the valve casing and extend into the telly openingand having an opening at its top for the valve casing and a valve capportion adapted to engage the valve casing to hold the dust cap portionin place.

3. In combination, a wheel telly having an opening therein adapted toreceive a tire valve casing, a valve casing of somewhat smaller diameterthan lthe opening, extendin therethrough, tand a dust cap for the vva vecasing having a part extending into the felloel opening, said dust capbeing adapted to slide down over the valve casing and extend into thefelly opening and means at the top of the dust cap for engaging thevalve casing to hold the dust cap thereon.

4. In combination, a wheel felly having an opening therein adapted toreceive a tire lvalve casing, a valve casing of somewhat smallerdiameter than the opening, extendino` therethrough,"' and a dust cap forthe va ve casing havinga part extending into the elloe opening, saiddust cap being adapted to slide down over the valve casing and extendinto the felly opening, means for engaging the valve casing to hold thedust cap thereon and means near the top of the cap for limiting thedownward movement of the dust cap over the valve casing. v

5. In combination, a wheel felly having an opening therein adapted toreceive a tire valve casing, a valve casing of somewhat smaller diameterthan the opening, extendino` therethrough, and a dust cap for the va vecasing having a part extending into the felloe opening, said 'dust capbeing adapted to slide down over the valve casing and extend into thefelly opening, means for engaging the valve casing to hold the dust capthereon and a packing forming a leaktight joint between the valve casingand the dust cap.

In witness whereof, I have hereunto signed my name.
